Abstract
An example system in accordance with an aspect of the present disclosure includes an opening assembly and a guard assembly installable in a floor above an enclosed region. The opening assembly is actuatable between an open configuration to provide access to the enclosed region, and a closed configuration in which the opening assembly provides a closed surface. A guard assembly is mounted to the opening assembly and actuatable independent of the opening assembly, between a retracted configuration flush with the closed surface of the opening assembly, and a deployed configuration to serve as a guard for the opening assembly.
Claims19
A system comprising:
- a guard assembly actuatable between a retracted configuration and a deployed configuration to serve as a guard;
- the guard assembly including a plurality of shafts bound on their upper ends by an upper guard support and bound on their lower ends by a lower guard support;
- and
- a plurality of linear bearings to slidably engage the plurality of shafts of the guard assembly, and wherein at least one shaft of the plurality of shafts has a customized diameter profile comprising a non-constant diameter along a length of the at least one shaft;
- the customized diameter profile comprising multiple discrete changes in diameter along the shaft length, between a full diameter corresponding to being gripped securely by the linear bearings, and a reduced diameter allowing for slop between a linear bearing and the at least one shaft.
